外墙外保温系统是置于墙体外侧,以保温、防水、保护及装饰等性能为主要功能的复合墙体,一般是由多层具有不同特征和功能的材料通过合理组合排列布置而成,最终表现出良好的综合性能,但随着外保温系统的广泛应用其面层开裂、空鼓等现象成为外墙外保温系统主要矛盾之一,保温体系一旦发生开裂现象则性能将发生很大改变,不仅不能满足设计要求甚至会危及墙体安全,因此充分分析裂缝形成原因并针对性的提出解决措施具有重要意义。
Exterior wall insulation system is placed outside the wall, with insulation, waterproofing, protection and decorative properties as the main function of the composite wall, usually by a number of different characteristics and functions of the material through a reasonable combination of arrangement, Eventually showing a good overall performance, but with the widespread application of external insulation system surface cracking, hollowing and other phenomena become the main external insulation system, one of the insulation system in the event of cracking phenomenon will greatly change the performance , Not only can not meet the design requirements and even endanger the safety of the wall, it is of great significance to fully analyze the causes of the formation of fractures and propose solutions to the problems.
